Nice bro aaj tak you tube ka bahut axa lecture
Good sir this is important for life . Thank you sir your help sir better
Thanks
From Australia
sir mein bhout confuse tha top extra bar nikalny k liye thanks a lot sir
Thanks for making me civil engineer.
Waoo sir good job keep it up and thankyou 🥰🥰
Thank n Sir me apse bhtttt kuch seekh rah hu
Thanks you for provide very clear concept
Ap length center sy ly rahy ho or l/4 face sy provide krrahy ho ?
Very good sir
Sir ji aap great ho.
Thank you so much sir
Very very very good knowledge.
Thanku Sir❤❤❤
Thanks for teaching sir
Best video sir
Sir thanks for this vidio...but..digram me dusre side me dekho 0=15L likha he..baki pura samj aaya he...or ak vidio banayiye same pr dusra site+digram+blank papers pe samjayiye..clrly...
Utube me aapki taraha kisine nahi samjaya he..but one more try...u get outstanding vidio...
Or ha c/c se samjayiye colom konsa bhi size ka raha to problem nhi hoga
Very nicely explained
Bbs calculated karte hai staircase beam slab ya video lekar aaoo
jld brother
In which case bottom extra is more than top extra other than cantilever beam ?? Plz explain and also what about secondary beam resting on primary beam what about its development length
Main longitudinal reinforcement in beam.
According to which code?
Will cover come in lap length- In simply support beam or in continuins beam in BBS calculation ?
Sir 510 ka pura dege to cover kaise milega beam me..
What if my beam depth is 400mm..How to give 510 as ld
Good 🎉sir
Thanku sooooo much sir,for your coapration
Sir apne is series me ek jagah bataya hai
*stirrups m spacing +, - 15mm & cover block me +, - 10mm ka tolerance chalta hai IS CODE me dia hai.
Sir yh IS CODE m kaha dia hai.
Please mention kriye.
thanks....sir ji
Sir in L/4 we take L= Clear span you told in video to take effective span .Which one is correct
See in drawing detail L is effective span and not clear span. Spa
Brick work section read method
Great video
@10:08
Sir you are wrong.
We shouldn't provide lap upto 2D for bottom rebar.
Hello sir
Kya aap aese aur drawings de sakte hai mujhe practise ke liye
Sir kya ghar ke liye pile foundation thik hai ya footing kar ke column karte hai woh 🙏🙏🙏
Love you Sir.......
Good evening sir
Good evening
Sir beam mai strips jo hai unka hook jo aata hai wo kis taraf ana chahiy uper ki taraf ya niche kai tarf?
Thanks
Sir, drawing or design krne k baad site pe execution ki vedio b daalna..🙏
Ld=(0.87fy)xdia/(4 Tbd)
Development length ka formula ye haina syllabus me to ye bataya tha?
Please clear my doubt
Ap bhtt accha smjhate ho bhai
great sir
Can you say me which is code are you use sir bcz this all formula not fit in our Structure design.
Sir colum ka bbs bataye plz
Less also bend from deployment lenght
Sir apne column ka reinf ke bare mai Nhi btaya...column reinf 40 mm pe phir beam reinf 25 mm ke cover pe ayega
Sir... Thank you... 👌👌🙏🙏
very nice
Make videos pile to rectangular column conversion
Development length mai column 400x300 ka hai, 960-250=710
400 mai 710 kese hoga
Structure se related video please sir ji
Sir video quality badayiye
Sir beam Ka schedule drawing kya aap mujhe de skate hai
Sir Aapka beam ka depth 500 ka toh fir 510 ka steel kaise provide karoge ......kya sir kuch b bak rehe ho .........LD me hi sab Ho jayega sir , 10d ka koi jarurat nehi hai .
Good
Sir 20 minut wala video dikhie
phi*fe/4tbd is this the second formula?
Achi video
Sir -510 hoo to beam ka size kitna
Column ka bbs video ek upload karo sir ji
if a beam B1 is connecting to a Col from one side and another beam B2 is connecting from opposite side of col. And both beams details is different B1 has 3 Top continues bars and B2 has 4 Top continous bars how will we provide development length and will B2 continues bars extend into B1 or not plzzzzzzz someone .....
tq sir🙏
welcome
Thanks for your great support sir.its really more helpfull for freshers .👍👍👍
Galat teach kar rehe hai wo aur tum great bol rehe ho
sir beam ki depth 500 hai to 510 kaise aaya please samjhao
Sir 20 minutes wala video chaheye hum ko..
L ka value 500 kis ke according le liye
Sir L d ki value comp aur tension member k liye 1 formula h us s development length find k जाती है
uspe b video hai dekho channel meh
@@civilsitevisit usme 49D h and grade M25 h.
@@civilsitevisit sir job hai to hum logo Ko bulaeye
Please make a video footing and foundation work.. Thx you
What is spacing length?
Do over head tanks design also steel details
Building slab casting ke liye knsa cement use kare OPC or PPC
Use ppc it has more strength than opc.....
L/7 ke bare me bataiye
But our beam depth is 500 how we can provide 510🤔
That extra length will go in column.
@@tafzeelqureshi5444 but column fill till the bottom of beam... So we have only 500mm depth if we assume 40 mm cover from top then 40 mm also subtract from 500mm🤔
@@sajidshaikh1502 exactly
First we have all drawing details and development length is also mentioned. So that column is fill up to that point where development length is apply.
@@sajidshaikh1502 this question answerable by only experienced civil engineer. This man didn't have any practical knowledge. Only book knowledge
3:55 top extra bars
Why we dnt apply direct 60 db that equal to 50d +10 d
yes but in many cases it goes wrong
Thanku so much sir
@@civilsitevisit please elobarate.
Why 50d?
Ye 10 db samajh me nhi aya sir pliz kaha se aya 10db
Ye 10d he..
When depth of beam is 500mm how is it possible to provide 510 mm devlopment length as you calculated
deveelepment length galat nikali
The development length at column beam junction of bottom bars has no issue because they can go through the height of column
@@xahidmushtaq4062 what about strip footing with eccentric wall with only 150mm spacing from the exterior face of wall to the exterior face of strip
Bottom extra ko L/7 kaise lete hai kanhi kanhi drawing pe diya rahta hai
Top extra ka bhi nikalo
nikala top extra ka b
keep it
But sir IS 13920-2003 clause 6.2.6 said we can't provide lap in confining zone.
Due to seismic zone k movement के karan column k inner face se hame 2D (D= effective depth of beam) हट्टाना पड़ेगा.
And also IS code said we can't provide lap जाहा Positive Bending Movement Over 50%..???
But apne video me btaya lap hmm center se 0.15L pr provide krenge...but IS code toh isake liye mnaaa krtaa h....
Yes you r correct , we can't provide lap @ 0.15L from support, IS 13920 clearly mentioned that
@10:08
Sir we shouldn't provide lapping upto 2D for bottom rebar.
Please you read carefully codebook
0.10*l kaha se aata hai dor
Maximum length of beam and column
500 mm depth he column ki to 510 mm kese ho sakta he...
0.15L?
Why did u take only 1 side cover? Its 50 cover so u have to take bothe side
Why depth of beam is always larger than width ?
Not always
I have seen a beam of 30 inches width and 24 inches depth at site.
Sir ji good evening video clean please🙏
Development length wala
450 beam me agar 16 mm ka daya aaya toh 510 kaise ayega
minus kar lo jo b ayega
calculation meh glti ho sakti hai check karo
300/500 beam mein development length ka baki 510 mm AAP kaha dalenge.. calculation galat hai
Are vai column ke andar jayega
Appki beam ki depth hi 500 h, to 510 kese denge development length
Total 870mm se jyada idhar development length nahi diya ja sakta
Ld+10db many sir mana jitna bhi kam kiya ha usma follow hi nhi kiya ha
Ye 10db kaise aya bhai mukhe to nhi aya samajh me bata do bhai
I know Steel working
❤️❤️❤️
Very naice ❤🫶👌🌹✍️🙏
Sir please provide me this drawing in pdf form
I'm waiting so long time
